Make your results useful
Your result is feedback on this set, not a prediction of your real exam score. Separate gaps in understanding from questions that were correct but took too long.
- Finish a set without checking the lesson during the test.
- Review incorrect and unanswered questions.
- Read the explanation and identify the step you missed.
- Practice another question using the same skill before trying a new timed set.
Practice with a timer
Read the question carefully, keep track of units and mark difficult questions to revisit. If a method takes too long, practice the individual steps without a timer before trying them under time pressure.
Lessons to start with
- Synonyms: Similar Meanings — Choose the word with the closest meaning
- Fractions — Work with parts of a whole
- Gears: Direction & Speed — Which way gears turn and how fast they move
